Nevertheless the shadow of desperate war hung over the West. Neither the northern nor the southern Indians were yet subdued; sullen and angry they watched the growth of the whites, alert to seize a favorable moment to make one last appeal to arms before surrendering their hunting grounds. Moreover in New Orleans and Detroit the Westerners possessed two outposts which it would be difficult to retain in the event of war with England, the only European nation that had power seriously to injure them. These two outposts were sundered from the rest of the settled Western territory by vast regions tenanted only by warlike Indian tribes. Detroit was most in danger from the Indians, the British being powerless against it unless in alliance with the formidable tribes that had so long battled against American supremacy. Their superb navy gave the British the power to attack New Orleans at will. The Westerners could rally to the aid of New Orleans much more easily than to the aid of Detroit; for the Mississippi offered a sure channel of communication, and New Orleans, unlike Detroit, possessed some capacity for self-defence; whereas the difficulties of transit through the Indian-haunted wilderness south of the Great Lakes were certain to cause endless dangers and delays if it became necessary for the Westerners either to reinforce or to recapture the little city which commanded the straits between Huron and Erie. During the dozen years which opened with Wayne's campaigns, saw the treaties of Jay and Pinckney, and closed with the explorations of Lewis, Clarke, and Pike, the West had grown with the growth of a giant, and for the first time had achieved peace; but it was not yet safe from danger of outside attack. The territories which had been won by war from the Indians and by treaty from Spain, France, and England, and which had been partially explored, were not yet entirely our own. Much had been accomplished by the deeds of the Indian-fighters, treaty-makers, and wilderness-wanderers; far more had been accomplished by the steady push of the settler folk themselves, as they thrust ever westward, and carved states out of the forest and the prairie; but much yet remained to be done before the West would reach its natural limits, would free itself forever from the pressure of outside foes, and would fill from frontier to frontier with populous commonwealths of its own citizens. THE END OF VOL. IV. APPENDIX It is a pleasure to be able to say that the valuable Robertson manuscripts are now in course of publication, under the direction of a most competent editor in the person of Mr. W. R. Garrett, Ph.D. They are appearing in the _American Historical Magazine_, at Nashville, Tennessee; the first instalment appeared in January, and the second in April, 1896. The _Magazine_ is doing excellent work, exactly where this work is needed; and it could not render a better service to the study of American history than by printing these Robertson papers.
